Do the clutch cable as well. A little on the speedo and tacho cables also helps but not much or you risk spinning it into the speedo/tacho clock mechanisms.

Thanks Sesman and Ted.

After sticking it in the vice, applying a little heat, threatening it with long handled grips and lots of trial and error I've got to this.....
Hopefully that will be a lot better on the bike

What I found with mine after I removed it completely for inspection and light oiling, was that there were no kinks or bad bends, but that the inner lining must have melted and expanded causing the inner cable to bind, even after running oil right through.  Worth checking if you stiil have some friction over the full travel before you refit it.

In view if this I have routed the new cable so that it does not go through the "Guide Eye" on the cambox cover, which will reduce any heat transfer from a hot cylinder head vicinity. Checking the cable after a good run confirms it is not getting hot now.

Hi Guys,

I was half asleep I think when I read it !!!

It was the CLUTCH CABLE  I was referrring to !!!

Just testing to see if you were all awake  ;D ;D

So just read it in the context of the clutch cable.

Cheers

The attached pic from the 400F Setup Manual may help:

That cable guide on the horn is called "Clamp, Clutch Wire" in the parts fiche, but from the pic it seems the throttle cables go through there too.

The throttle cables go through the guide attached to the horn bracket.
I didn't realise that existed until now, does it matter much?
